Here are 15 fascinating facts about North Korea, one of the most isolated and ruthlessly ruled nations on earth:
1. The founder and first leader of North Korea, Kim Il Sung, created the country's policy of juche or "self-reliance," which cut off North Korea economically and diplomatically from the rest of the world, even in times of great need, such as famines.

3. During its seven-decade existence, North Korea has been ruled by three generations of the same family, all brutal dictators. Kim Jong Un, 33, grandson of Kim Il Sung, came to power in 2011, following the death of his father, Kim Jong Il.
4. Between 150,000 and 200,000 North Koreans live in prison camps surrounded by electrified fencing, according to South Korean government estimates and Human Rights Watch. The worst camps are for those who commit political crimes, and offenders can have their entire extended family imprisoned with them. As many as 40% of camp prisoners die from malnutrition while doing mining, logging and agricultural work with rudimentary tools in harsh conditions, according to a 2011 Amnesty International report.

However, the United States doubted that claim. The North is believed to have an arsenal of nuclear weapons but the size is unknown.
